/* immark.c
 * This is the implementation of the build-in mark message input module.

 * NOTE: read comments in module-template.h to understand how this file
 *       works!
 *
 * File begun on 2007-07-20 by RGerhards (extracted from syslogd.c)
 * This file is under development and has not yet arrived at being fully
 * self-contained and a real object. So far, it is mostly an excerpt
 * of the "old" message code without any modifications. However, it
 * helps to have things at the right place one we go to the meat of it.

 * This code must simply spawn emit a mark message at each mark interval.
 * We are running on our own thread, so this is extremely easy: we just
 * sleep MarkInterval seconds and each time we awake, we inject the message.
